Taking a bit of a wander back through some of the classic crime fiction authors, I've been reading a few Simenon's. In Maigret's Boyhood Friend, Inspector Maigret receives a visit from his old school friend Leon Florentin. Florentin had been the class clown, and despite only seeing him once since their childhood, Maigret can remember him well. Now, although, nobody is laughing as Florentin's mistress has been shot dead in her apartment, whilst Florentin was there and, not surprisingly, he is now the prime suspect in her murder.
